The I-90 Series slewing rings represent a significant technological milestone in heavy-duty industrial transport components, uniquely certified for road use. Specifically designed to meet the most demanding industrial requirements, the I-90 slewing rings are recognised for their robustness, reliability, and adaptability.
The I-90 Series comes in two main versions:
The I-90, featuring a single ball-bearing row
The I-90/2, equipped with a double ball-bearing row.
oth versions feature a uniform profile height of 90 mm, designed to ensure compactness and stability in industrial trailers and operational machinery. The external diameter for the single ball-bearing I-90 ranges from 1000 mm to 1300 mm, while the double ball-bearing I-90/2 ranges from 994 mm to 1194 mm.
They efficiently support axial loads of up to 200 kN, offering maximum safety even under the most demanding operating conditions.
A distinguishing feature of the I-90 slewing rings is their high level of customisation.
Each slewing ring can be specifically configured according to technical requirements, including bespoke drilling patterns, diameters, and load capacities. This flexible approach ensures each component perfectly integrates with specific application needs, enhancing the efficiency and longevity of the final product.
Additionally, the I-90 and I-90/2 slewing rings fully comply with the new UNI EN ISO 5216:2024 standard, exclusively dedicated to trailer ball-bearing slewing rings. This standard clearly defines the essential design, performance, and safety requirements of this critical component, significantly improving reliability in heavy-duty transportation and load handling.
SIRCA SA – RIMA GROUP’s role as Project Leader in developing the UNI EN ISO 5216:2024 standard within the international ISO/TC 22/SC 40/WG 1 committee underlines the company’s unwavering commitment to innovation, quality, and safety. The collaboration with Europe’s leading manufacturers has established high standards, laying the groundwork for enhanced safety and efficiency in heavy-duty industrial transport.
Therefore, the I-90 Series slewing rings represent an ideal solution for manufacturers and operators requiring high-performance standards, regulatory compliance, and customisation potential. The quality assured by the RIMA Group makes these slewing rings an advanced technical solution, perfectly suited to meet the most complex challenges in industrial sectors and road mobility.
